The article presents the results of experimental researches conducted for the first time in Romania, in the Research and Testing Laboratory of Reinforced Concrete  from Technical University of Civil Engineering Bucharest, Romania, in order to study the possibility to apply in Romania a new European evaluation criteria of concretes freeze-thaw resistance, concrete mixes with different cement types. Concrete freeze-thaw resistance was evaluated applying the standard methods on European level (CEN/TS 12390-9, CEN/TR 15177) depending on the calculation of the scaled material quantity and on determination of dynamic elastic modulus values of concrete samples tested on repeated standard freeze-thaw cycles. The mass reducing of the concrete samples and  dynamic elastic modulus are compared with proposed limit values, depending on the situation in one of XF exposure class.
